The Houston Independent School District police increased patrols around Frank Black Middle School. The step up in security follows an alarming situation Wednesday.

The school's principal said a man exposed himself to a student as they walked to school. In an audio message sent to parents, the principal said the disturbing behavior unfolded on Judiway Street and East T.C. Jester Blvd.

Anyone with information on the man's identity should contact the HISD police department.

HISD issued the following statement: "An investigation is underway after it was reported that an unknown man exposed himself to a student near the Black Middle School campus. The student ran away and made it to campus unharmed. The safety of our students is our top priority. As such, extra HISD Police officers have been assigned to patrol the area as a precautionary measure."
